Unless you’re expecting something to catch that exception and suppress the message, don’t log. Pythonic is not really a look as it is the formatting of code.
Why throw is used in Java?

You ensure your application can continue to operate normally with little impact on the user experience. In contrast, logging is a means of auditing to keep track of things happening within an application.
How are errors handled in client side logging?
Since these logs are client-side, all errors experienced by users will be lost in their own browsers. This means that the only way we can find out about errors in our application is by user reports, which often don’t happen; many users will simply leave rather than filling out a bug report.
How to implement Error Logging Modules and handlers ( ELMAH )?
How to implement Error Logging Modules and Handlers (ELMAH) error logging. ASP.NET applications must be able to handle errors that occur during execution in a consistent manner. ASP.NET uses the common language runtime (CLR), which provides a way of notifying applications of errors in a uniform way. When an error occurs, an exception is thrown.
How does an error handler work in ASP.NET?
To provide the error details to the user of the application, you must specifically write the error details to the page. You would typically use a page-level error handler to log unhandled errors or to take the user to a page that can display helpful information. This code example shows a handler for the Error event in an ASP.NET Web page.
